Research on Transformer Winding Deformation and Winding Resistance
DEStech Transactions on Environment, Energy and Earth Science, 2016 In this paper, the influence of transformer winding deformation on the equivalent electrical parameters is studied, and the proximity effect and skin effect caused by AC current in the wire are simulated. It is verified that the current distribution will be affected by the proximity effect and skin effect.

SFRA, Detect of Winding Deformation in Power Transformer
International Journal of Innovative Technology and Exploring Engineering, 2020 The sweep frequency response analysis is extensively used technique for detect hidden fault and condition monitoring of power transformer. The operation is administered by supply a coffee voltage signal of varying frequencies to the transformer windings and measuring both the input and output signals.

Methodology to locate and quantify radial winding deformation in power transformers
High Voltage, 2017 Frequency response analysis (FRA) is a tool that can be used to detect changes within the structural geometry of a transformer. One application of FRA is to detect winding displacement after the transformer experiences an overcurrent event.
